Erik O. Kimbrough, PhD, is an Associate Professor of Economics in the Smith Institute for Political Economy and Philosophy at Chapman University’s Argyros School of Business and Economics. Kimbrough’s research uses experiments to study the economics of rule-following, social norms, conflict resolution, cooperation and institutions, among other topics. I’ll be helping to design and analyze some experiments to understand cross-cultural variation in the degree of in-group and kin favoritism.
